WHO head indicates full flu pandemic to be declared

The World Health Organization is likely to raise its flu alert to the top of its six-point scale and declare a pandemic, its director-general indicated in an interview published on Monday.

In remarks setting the scene for another alert increase, but without saying when, WHO chief Margaret Chan warned against over-confidence following a stabilization in the number of new cases of the H1N1 strain that has proved deadly in Mexico.

"Level 6 does not mean, in any way, that we are facing the end of the world. It is important to make this clear because (otherwise) when we announce level 6 it will cause an unnecessary panic," she told Spanish newspaper El Pais.
